I class myself as a semi pro musician. My logic behind this is I have a day job still but every week (mostly weekends) I am playing three or four gigs, I am getting paid for these gigs, I am booked by establishments or members of the public be it weddings, parties, events, clubs etc. and are paying me for this service. I have done 118 gigs this year and have been paid but not enough to support me fully and give up the day job. I consider this semi pro.
